Hi everyone,
I’m currently unable to to effectively update Grub2. I’m running tests on Leap 16 in a VM (UEFI, Full Disc Encryption and TPM 2.0). I’ve tried to reduce grub time out to 1 second but it doesn’t work. I edit /etc/default/grub and run sudo grub2-mkconfig -o /boot/grub2/config.cfg the output message is correct:
frederic@leap-vm:~> sudo grub2-mkconfig -o /boot/grub2/config.cfg
Generating grub configuration file ...

Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.
Adding boot menu entry for UEFI Firmware Settings ...
done
But after reboot the timeout is still the default 8 seconds. What am I missing?
